A pinpoint depression where two or more grooves meet? - Correct Answer pit
A shallow, linear depression in a tooth is called a: - Correct Answer A groove
A small elevation on the lingual surface of a maxillary central incisor: - Correct Answer Cingulum
A thin layer of uncured resin remains on the surface after its cured so new layers can bond to existing layer, what is
this layer called? - Correct Answer Air inhibited layer
A three-cusp type mandibular second premolar often has: - Correct Answer A "Y" shaped groove pattern
A triangular ridge - Correct Answer cusp ridge that descends from the cusp tips toward the central part of occlusal
table
A wedge is used to - Correct Answer Prevent overhang/ to adapt the band to the cervical region of the tooth
Acid etch technique - Correct Answer the enamel is treated with phosphoric acid about 37% to produce micro-
porosities for the resin to flow into
-helps form a mechanical bond between resin and enamel-reduces microleakage
An oblique ridge can be found on: - Correct Answer Maxillary 1st molars
An unfilled sealant material will self adjust and a filled sealant material will need adjusted - Correct Answer True
Anatomical crown: - Correct Answer Portion of the tooth that is covered with enamel
Bases and liners can be used as - Correct Answer sealers,reinforcers,insulators,obtundents, and pulp stimulators
Between the tooth and bonding agent: - Correct Answer Mechanical retention
cementum of tooth - Correct Answer hard connective tissue
fastens tooth securely in the socket
Chemical retention - Correct Answer bonding between tooth & material
Class I molar relationship - Correct Answer mesiobuccal cusp of the maxillary first molar is positioned in the buccal
groove of the first molar
Class II molar relationship - Correct Answer buccal groove of the mandibular first permanent molar is distal to the
mesiobuccal cusp of the maxillary first permanent molar by at least the width of a premolar
Clinical crown: - Correct Answer That portion of the tooth that is visible in the oral cavity
Contact areas serve two purposes - Correct Answer Stabilize dental arch, to keep food from packing between the
teeth.
, Convexity running from the distobuccal cusp to the mesiolingual cusp - Correct Answer Oblique Ridge
Corrosion: - Correct Answer Break down of amalgam by acids
Creep - Correct Answer The slow change in dimensions of the amalgam due to prolonged exposure to stress.
cross bite - Correct Answer When the mandibular teeth are outside (facial/ buccal) of the maxillary teeth
Delayed expansion in amalgam materials due to moisture contamination is eliminated by: - Correct Answer The
removal of Zinc from the alloy
Dental Amalgam Alloy - Correct Answer An alloy of silver, copper, tin, and zinc powder particles or as a compressed
pellet.
EFDA's renew licenses every? - Correct Answer March 31st - odd years!
enamel hypoplasia - Correct Answer incomplete development of tooth enamel
Excess mercury is brought to the surface of the amalgam when during... - Correct Answer condensation/ polishing
Galvanism - Correct Answer An electrical current generated by dissimilar metals in an acidic environment
Have the ability to soothe the pulp sensitivity: - Correct Answer Obtundents
If saliva contaminates the tooth during the placement of a sealant, one should: - Correct Answer re-etch the tooth for
10 seconds.
Incomplete closure of the lobes coming together - Correct Answer Fissure
inner nut - Correct Answer Adjusts the size of the matrix band loop
Insulators - Correct Answer Also referred to as bases (cements used in thick layers) and are placed to insulate the
pulp from thermal irritation.
Interproximal spaces between teeth - Correct Answer gingival papillae
Its composition is around 95% inorganic matter, mainly hydroxyapatite, and 5% organic matter and water: - Correct
Answer Enamel
Major depressions on both anterior and posterior teeth - Correct Answer Fossae
Material that can be used as either cement or restorative material in a class V lesion - Correct Answer Glass Ionomer
Maxillary 1st premolar #4/13 sometimes have: - Correct Answer 2 roots 1 buccal, 1 lingual
Mechanical retention - Correct Answer between the tooth and bonding agent
Mercury to alloy ratio - Correct Answer - the amount of mercury that is mixed with the amalgam alloy
- more mercury increases the mercury-containing reaction products
- minimizing mercury results in an improved restoration
- strength is increased
- marginal breakdown is decreased
- inadequate mercury/alloy ratio = voids in the restoration
Minimal depth restoration - Correct Answer 0.5mm to 1.5mm
Most sealant material is made of what? - Correct Answer BIS-GMA for strength
Mottled enamel - Correct Answer another name for dental fluorosis
Movement of the jaw from left to right: - Correct Answer Excursive movements
